This report presents findings from a cooperative USF/URS/FDOT research study undertaken to develop design rules for double composite steel bridges. In the study, a 48 ft long, 16 ft wide, 4 ft. 10⅛ in. deep trapezoidal HPS 70W box section designed to AASHTO’s LRFD 2004 specifications was fabricated and tested. The section has an 8 in. thick top slab and a 7 in. thick bottom slab and represented the entire negative moment region of a full-size, continuous bridge. The specimen was tested to evaluate fatigue, service and ultimate provisions of the AASHTO code. Instrumentation was provided to monitor load, strain, …
